The reason for its existence at all is simply a superstitious belief that everywhere prevails that evil spirits who are at war with mankind have special power to work mischief along roads that have no turnings in them. Mad with glee, they fly swifter than the wind along them, and woe betide anything that lies in their course whilst they are careering along. It is for this reason that the owners of the house that abuts on this racecourse of the gods hasten to put up the stone with its three-worded inscription in order to avoid the baleful effects of their coming full tilt against it. Some calamity, they believe, would certainly be the result, but no sooner do the spirits see the words "I dare defy," than, paralyzed with fear, and trembling at the mystic words that have struck terror into them, they fly in disorder from the scene. The Chinese on the whole are endowed with broad common-sense, and in anything that has to do with money-making or with commercial matters they are as wideawake and as shrewd as a canny Scotsman or a Yorkshireman. They are gifted, too, with a keen sense of humour, and yet when they come to deal with the question of spirits and ghosts and ogres, they seem to lose their reasoning faculties, and to believe in the most outrageous things that a mind with an ordinary power of perception of the ludicrous would shrink from admitting. Quietly sauntering along by a road that skirts a hill, a rock is pointed out that plays an important part in the fortunes of the town that may be seen stretching away over the plain in front of us. Looked at from a certain angle it certainly conveys to one the impression that it is a huge crouching tiger. It has a defiant look about it, and an air of alertness, as though some enemy were about, that it must be on its guard against. Its gaze is fixed on the smokeless city, from which no sound can be heard and which would seem to be a veritable abode of the dead. It turns out that this great stone brute that nature has so deftly chiselled is the presiding genius of the city that lies so silently in front. The Chinese believe that objects in natural life which, by a freak of fortune, have any resemblance to bird or beast are inhabited by the spirits of that animal, and have all the natural powers of such, only in a greatly intensified degree. The physical strength of the tiger and its naturally ferocious character make it an object of dread, and so when a district is found to possess the figure of such, only in an immensely exaggerated size, then it is seized upon as the embodiment of physical and supernatural forces that can be used for the protection of a city or sometimes of a whole region many miles square.
